Answer: No. It's not proportional

Step-by-step explanation:

The direct proportion in mathematics is expressed as:

y = kx

where

y = $200

k = constant

x = $7.50

We then solve for k

y = kx

200 = 7.50k

k = 200/7.50

k = 26.67

Since k isn't a whole number, then the amount of money in her bank account proportional to the number of pumpkin she sells.

-------------add
-x = -2
x = 2

5x + 2y = 6
5(2) + 2y = 6

2y = 6 - 10
2y = -4
y = -4/2
y = -2 <=== here it is
